Jim, The Jython script engine returns its name as "python" for some reason, so that's what's displayed as the option, but it is definitely Jython not Python. If you want to run your script as-is and use stdout for the results, you can use ExecuteStreamCommand for that, otherwise Joe's references will show you how to interact with the NiFi API to read/write flow files, etc.
